Little Mix singer Perrie Edwards has one thing One Direction fans will surely covet: an engagement ring from boy-bander boyfriend Zayn Malik.

Edwards, 20, walked the red carpet with Malik, 20, at Tuesday's London premiere of "One Direction: This Is Us," showing off a bit of new bling on her left ring finger and sparking speculation the two were engaged.

A rep for One Direction confirmed the rumors to MTV News saying, "Zayn and Perrie are engaged, but any further detail regarding their relationship is private."

But that didn't stop Edwards' mother from spilling some intel to the UK's Real Radio.

"Yes, it is. It's true. They got engaged on Sunday and it was absolutely lovely," she said. "It's wonderful because Zayn is absolutely gorgeous and Perrie loves him to pieces, so it's just perfect. They just get on so well together and they understand each other, so it's just fabulous."

Avid One Direction fans probably saw the engagement coming. Just two months ago, Malik expressed his love for his Edwards in one of the most permanent ways possible: with a tattoo. 1D's tattoo artist told MTV News the female on his forearm was meant to be a "comic-style" version of his girlfriend.

The news sparked several worldwide trending topics Wednesday on Twitter, including #CongratsZayneAndPerrie and Zayn Malik.

Edwards and Malik began dating in 2011 after meeting backstage during the British "X Factor," which Edwards' girl group Little Mix won.

It's been a busy summer for Malik's One Direction. In addition to premiering their Morgan Spurlock-directed 3-D biopic, the band has been on tour in support of their second studio album Take Me Home. The guys' "Best Song Ever" is also up for a Best Song of Summer Moonman at this year's MTV Video Music Awards, airing live on August 25 at 9 p.m. ET.
